Applica/:iw filed November 23, 1922.

To all 'whom it may concern:

Be it known that I, ALBERT M. OsLooK, a citizen of the United States, residing at Elgin. in the county of Kane and State of '5 Illinois, have invented certain new and useful Improvements in Odometer Constructions, of which the following is a specification.

rlhis invention relates to improvements in odometer construction and has for an object to provide a new and improved form of odometer in which the movement of a rotating element, or the like'may be eliiciently and satisfactorily transmitted to and registered by the Vindicating elements.

. Another object consists in the specific arrangement and construction of the odometer and allied elements.

Another object consists in the means to set the reset or trip odometer. These and other objects will be more fully described and disclosed in the following specification and shown in the accompanying drawings in which- 'Figure 1 is a front elevation of an odometer, comprising total mileage and trip sections, a portion .of the reset mechanism being shown in section'for clearness;

Fig. 2 is a transverse section along the line 2 2 of Fig. 1;

Fig. 8 is a vertical section along the line 3 3 of Fig. 1. l

Fig. 4 is a transverse section taken along the line 4 4 of Fig. 3.

Fig. 5 is a side elevation of a gear secured to the first wheel of the total mileage section;

Fig. 6 is a front elevation of the driving mechanism, portions' of the same being shown in section for clearness;

Fig. 7 is a vertical section. taken along the line. 7 7 of Fig. 1; and

Fig. 8 is a horizontal section taken along the line 8 8 of Fig. 7.

Like numerals refer to like elements throughout the drawings in which ldesignates the back wall or'frame of the instrument, which projects outwardly 'from the bearing brackets 11 12, see Fig. 1, and a central bracket or pedestal 13, see Figs. 1

and 7. Extending between and mounted in Serial No. 802,735.

the end bracket 11 and center bracket 13 is a shaft 'l5 held against removal or accidental displacement by means of the screw head 16, see Fig. '1. 15 is the hollow sleeve 18 upon which are mounted the unit mile-age indicator wheel 19 and a plurality of additional indicator wheels indicated by numerals 20. Secured to the sleeve 18 outwardly of the indicator wheels 2O is the collar 21, see Figs. 2 and 3, for example, this collar being provided with the slotted projection 21a and the upstruck lug or tongue 21h, the latter fitting a keyway 15a in the sleeve 18. Extending through a threaded aperture in the bracket 1l, is the adjusting screw 23 having an eccentric portion 23a fitting the slot in the collar 21. It will be apparent that rotation of the screw 28 will operate to partially rotate the collar 21 and sleeve 18.. This partial rotation will be communicated to the mileage wheels 20 through carry-over mechanism, not shown. The purpose of this construction is to permit the alinement of the numerals on vthe total mileage indicator with those of the trip indicating wheels, not yet described, where inaccuracies in manufacture result in a partial misalinement. The shaft 15 is recessed at 15b at one extremity and a coil spring 25 is mounted therein.

The sleeve 18 is provided with a collar or washer 26 at its inner extremity. Secured between this collar 26 and the bracket 13 is the gear member 27 having a toothed flange 27*1 at one side and inclined arms 27b toothed or corrugated at 27c at their extremities at the other side. These toothed extremities 27c mesh with and engage teeth 19l at one side of the unit wheel 19 in a manner similar to that shown in Fig. 4.

earings 28 and 29 extend upwardly from the wall 10 at either side of the bracket 13 and in these bearings is journaled a shaft 30, sec Figs. 1, 7 and 8. Carried by this shaft 30 outside the bearing 28 is the worm gear 31 in mesh with and actuated by the worm 32, carried on shaft 83, which latter shaft is also provided with the worm gear 34 actuated by the worm 35, see Fig.4 1 for example. This worm 35 is carried upon the shaft 36 which also carries the worm gear 37, which Mounted on the shaft 45, see Figs. 7 and 8, for example.

is in mesh with a worm 38, carried upon the main ldrive shaft 39. which is seated in the sleeve 40, extending through and engaged by the ring flange. 41 of the base 10, see' Fig. 6.

Journaled in the bracket 13 is the pinion shaft 43, carrying at one side of the bracket the pinion 44, and at the other side of the bracket the pinion 45. Pinion 44 meshes with a gear 45 carried upon a hub 46, which is carried by and secured to the shaft 30. The rotatable disk 47 is also carried by the hub 46, this disk being cut away at one side and provided with a pair of teeth 47, meshable at each revolution with'teeth on inion inion 45 is in mesh withv teeth l27a of the ar member 27 and it will be apparent that disk gear 47, when continuously rotated by the shaft 3() will on every revolution advance or move the pinion 45 a portion of a revolution, which movement will be transmitted to gear 27. By properly constructing the members, this movement will correspond to one division of the indicator wheel 19, the lsaine being usually divided into ten indications representing one to ten miles, the disk 47 making one rotation ,per mile of travel on the vehicle on which it is attached. Carry-over mechanism of any suitable construction may be mounted upon the sleeve 18 between the unit wheel 19 and the adjacent indicator Wheel 20, also between each of the succeeding indicator wheels to transmit, in well known manner. in ratio of one to ten, the revolutions of the adjacent wheel.

A shaft 50 is provided for the trip mileage group, this shaft 50 having an extension 50 fitting into the recess 15", of shaft 15 and being provided with a roughened or toothed portion 50b upon which is forced the hub of the gear 51. Mounted upon the shaft 50 also is the connector 52 having a hub forced into engagement with a toothed orroughened portion 50v of a shaft 50 and provided with teeth 52a or the like, at its extremities, see Figs. 3 and 4. This connector 52 meshes with internal teeth 54a of the tenths indicator wheel 55, which is rotatably mounted upon the sleeve 56, which in turn is mounted on shaft 50.. Sleeve'56 is collared or flanged at its extremities 56, 56, see Fig. 3, and rotatably mounted upon it are the additional trip indicator wheels 58, to which motion is successively applied by suitable carry-over mechanism from the tenths wheel 55 in well known manner. The flange 56a is extended for engagement with a stud or pin 57 by projectmg outwardly from the bracket 13, see Figs. 1 and 7, this engagement preventing rotation of the sleeve 56.

The shaft 50 is provided with an eXtension 50d extending through the bracket 12 and provided with ton es or lugs 50. Shaft 50 is also provid with a round tip 1. Journaled in this casing is the shi able stem 72 having the knurled cap 73 at its outer extremity. Secured to the stem 72 is bevelv gear 74 meshable with the ear 60, as shown in Fig. 1. Outwardly of t e ar 74 is the cam extension 72l of stem 72, aving a groove 72" therein into which projects tip 50t of extension 50l when the gears are in mesh, this serving to hold the stem 72 in position wherein the gears will mesh. The cam 72* is tapered from the grooves 72" towards its outer extremity.

When the stem 72 is movedto position shown in Fig. 1, the cam extension 72 shifts the sha-ft 50 toward the left against the action of spring 25, at the same time moving gear 51 out of mesh with inion '44. Tip 50t registering with groove 2" is held in such register by means of the spring 25, which, as stated', holds stem 73 in upward position, as viewed in Fi 1, wherein the shaft 50 may be rotated y means of the stem 72 for setting of the trip indicator wheels, as desired. When such setting has been accomplished, the stem 72 may be reshifted in mesh with gears 60 and 74 permitting mesh of gear 51 with pinion 44. This will permit mechanical drive of the trip odometer through the'mechanism previously described'.

This reset mechanism provides a quick and satisfactory means for setting or resetting the trip odometer which is especially desirable under present da conditions where touring is generally un ertaken with the assistance of route books identifying landmarks by mileage indication.

It will be obvious that my invention can be modified or altered and I do not wish to be restricted to the form shown and de-l scribed except as defined in-the appended claims.

What I claim is- 1. In combination, a normally stationary support, a plurality of indicator wheels rotatably mounted on said support, and means to rotatably adjust said support and indicator wheels to properly align said wheels as a unit relative to a window or the like.

2.
